This is my first time opening a deck builder tool kit and yes this is the Japanese version of the tool kit as I order this online without knowing the store also stock them. The tool kit will cost about $30 bnd from reader haven/urbangames and fanboys infinite but as of this post Fanboys infinite are sold out.
Well beside the box which you can use to store your card, you will also be given the rule card with a poster with some description and such (I don’t know how to read Japanese). You also will be given 4 booster pack, 1 from origin and the 3 pack will be random as some can be from nyx, theros and even M15. Beside from the 4 booster pack you will be given 4 pack of card, 2 of the pack will be land and the other 2 will be the bulk common and uncommon card and also some rare.
The 2 pack of land they give you also included 2 of each dual land and the rest are the basic land.
The other 2 pack give you the bulk common and uncommon and also 5 rare which is 1 from each color.
Here is what I got from the pack that was from this tool kit.
So far I found $30 for this tool kit a bit expensive especially when you got 4 booster pack and 3 of them are random as some of the set will be roll out of standard soon and if you are not a morden player the card will be kind of useless to you in standard in few month time. Beside from that everything seem good.
